which may cause skin disorders such as inflammation or
skin cancer, so care should be taken to avoid prolonged and
repeated contact with it. To remove used engine oil from
your skin, wash thoroughly with soap and water.
Do not leave used oil within the reach of children.
Dispose of used oil and used oil filters only in a safe and

CHECKING THE ENGINE OIL
LEVEL
62L004-4
With the engine at operating temperature and turned off, check
the oil level on the dipstick.
1. To get a true reading, the vehicle should be on a level spot. After
turning off the engine, wait a few minutes for the oil to drain back
into the bottom of the engine.
2. Pull out the dipstick, and wipe it clean with a rag.
3. Reinsert the dipstick and push it in as far as it will go, or the
reading will not be correct.
